The Sorcery of Ol'Hallow

All Sigma wanted, after successfully completing his latest Warlock hunt, was a bottle of liquor, the company of a couple of handsome men, and a good cigar to smoke in peace. But there's no rest for the Nullifier. In fact, his colleague Epsilon throws a new case on the table for him to solve. Sigma would rather avoid it, but the fact that it is not an official mission intrigues him, and when the woman confesses to him that the Warlock in question could be linked to the man's tragic past, he accepts without reservations.
Sigma thus finds himself in a remote village on the western border of the Kingdom of Fhalls: Ol'Hallow. There, a brutal murder was committed, and was disguised as a robbery. The man begins to investigate, but the hunt for the killer turns out to be tougher than expected. Above all because of a young man, Ciaran Vonlawstock, who Sigma just can't get out of his head. There would be nothing wrong, if it weren't for two problems: Ciaran is already engaged, and is the main suspect in the murders that continue to pile on in the village.
For the first time, after years of activity, Sigma faces the most painful crossroads in his life; should he follow the clues or his heart?
